Abstract: The past, present and future status of the Sediment Quality Triad (SQT) concept is reviewed. The SQT has developed since its inception; some early data interpretation methods remain useful and have been improved (e.g. normalising to reference data), others have not proven to be as useful as originally anticipated (e.g. a single index coupled with triangular graphical plots). SQT studies have extended to Antarctica, and the SQT concept coupled with weight of evidence forms a major basis for sediment ecological risk assessment. Future trends in the usage and utility of the SQT are suggested.
